Fujifilm EXR cameras -- that is, cameras with EXR sensors -- can use the software version of dynamic range enhancement technique on top of the EXR hardware dynamic range enhancement,

Only possible with the X series cameras in EXR mode (that is, the mode dial is turned to the EXR position) in positions DR800 and DR1600. When I get time I'll examine our F series images.

It works that way with the F70EXR. I never have felt an itch for DR800, as (hardware) DR400 on the F70EXR was such a giant leap forward from the resolutely DR100-is-all-you-get of our previous F30, we basked in the improvement and asked for nothing more.

There is a slight highlight benefit at DR800 but I found DR1600 to result in noticeably lower contrast images on a high contrast scene, which is not generally what most people want.\

This very high contrast (and backlit) scene could not have been captured with a non-EXR small sensor camera; at DR400, I got the shadows and the highlights with the 1/2" sensor F70EXR.

The red glow is a reflection from the vinyl table covering, a portion of which can be seen at the lower right.
